Letters Patent No. 91,846, dated' June 29, 1869.

IMPROVEMENT IN TENONING-MACHINE.

The Schedule referred to in these Letters Patent and making part of the eamo.

To all whom. it may concern.-

Be it known that I, LEVI S. HICKS, of the county oi' Peoria, and State of Illinois, have invented'a new and improved Tcnoning-Machine; and l do hereby declare that the following is a full, clear, and exact description oi' the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective View.

Figure 2 is a crosslsection.

Figure 3 is an elevation of left end of machine.

Figure 4 is a longitudinal elevation.

Figure 5 is an under-side View of link.

Figure is an cud view oi chain-way.

Figure T- is an end view oi link.

Figure 8 is a section of presser-bos.

Figure 9 is a view of link, showing feed-lng and slot.

Like letters in the figures of the drawings indicate like parts.

This invention has for its object to furnish an improved tenouing-inacl1ine, so constructed and arranged that the tenons may be cut upon both ends of the stuff, and at both sides ofthe ends at the same time, and upon stuiof any length, from six inches to tive feet and upward; also to furnish an automatic and constant feed, by means oi' two endless chains ruiming near their respective witter-heads, and assisted by a series of press- A are the legs, or supports of the machine. A' is the movable bed-plate, carrying the right-hand set, or cutters, chain-feed, Src.`

B is the frame and way;7 carrying the hed-plates.

C is the stationary bed plate, carrying .the nlachinery forleft-hand cutters and feed.

- D D are the two chain-ways.

E E are the friction-pul1eys7 bearing-chains.

F F are driving-pulleys on tlie driving-shaft'R.

G G are the endless chains.

H H are the presser-boxes, with shoes 7c.

I I are the vertical standards for cutting-gearing.

J J are the head-plates, carrying presser-boxes. K' and K are the tight and loose pulleys, to which the power is applied.

K is the driving-pulley for left-hand or stationary cutter-heads.

L is a conepulley, on main or counter-shaft.

M is the cone-pulley on cone-shaft.

N is the spur-pinion on cone-shat't. i

0 and P are spur-wheels, engaging with thc spurpiuion `N and the feed-shaft wheel Q, on the feedshaft R. p

S is a screw for regulating the distance between the two sets of cutter-heads.

T, hand-wheel of the screw S.

U and V are pulleys for driving the cutter-heads.

`W are tightenerepulleys.

each of the cutters and respective pulleys being sup-V ported by a horizontal shaft running in adjustable arbors, by which the distancebetween the cutter-heads m m is regulated. Y

Across the top, and connecting these guides I I, is the horizontal forked head-plate J, the arms of which project over the endless chain G.

v,lhrongh each end of these arms, a vertical handscrew passes, supporting the presser-box H, which may be from ten to twelve inches long and six inches deep, and of convenientwidth to carry a series of vertical presser-bars, z z z z.

These latter pass entirely through the box H, their lower ends terminating in'the shoes k L k k, whichmay be about one inch square, by about a half` inch thick.

Each shoe k presents, toward the front of the maf chine; abevelled edge, to admit the stuff beneath them and the chain G.

4 The bars z z,`&c., carrying the shoes, have each a collar around them, which rests'on the bottom ofthe presser-box. i

Between this collar and the ceiling of the box, a strong spiral spring, or its equivalent'winds around each bar, by which a strong pressure is maintained on the st-uc to be cut. The bars may be kept from turning in their sockets by making them square or with a spline.

On the inner side of this stationary bed-platel 0, is

the chain-way D, which resembles a trough, in the.

trough, or groove ot' which runs the lugs d d of the endless chain G, for the feed.

The chain-way lies athwart the bed-plate, from front to rear of the machine, and within a short distance of the cutter-heads in m,- and immediately under the presser-bars z z and shoes k.

The front and near ends of the chain-way partially bridge the chain pulleys E and F under its respective ends, in order to carry the lugs of' theI chain well on to the pulleys and cogs 1J.

The pulleys E and F are supported by arms n, projecting from the side of bed-plate under the chain way.

These pulleys. may be from six inches or upward, and have a series of teeth on their circumference, arranged in pairs, one of eachpair occupying the extreme edges of the pulley, yto admit between them the flat connecting-link e of the larger links of the chain.

-carrying the same squarely forward.'

The teeth are arranged around the pulleys at such intervals as to.properly engage each l-ink of the chain. The chain is driven by the rear pulley F, on the feed-shaft R, which shaft being spliued at its other end, also, carries the pulley F ofthe chain of the movable bed-plate A'.

The endless feed-chain G is compose-d of links ff, of a slab-shape, or oblong tables of iron j, about two and a half inches wide, by three and a half inches longr and three inches thick.'

Each tablet has two parallel lugs', (l d, onv the under side, with rounded corners, and curved in that part which passes on to the pulley.

Between the outer edge of the tablet of link and the lug is a space of from one-fourth to one-half of an inch wide, corresponding to the widt-hof the edges g g of the chain-Way on which this part slides.

The lugs are perforated through each end, to admit a bolt which unites them to the dat connectinglink ,e,V fThe lugs pass within the groove of the way, while the tablets slide on the top. o

Adjustable feed-lugs, a a a, Sac., with slots,v are bolted to the surface of every four or more ofthe tablets lj-opposite the corresponding feed-lugs Ion the other chain. These are to be adjusted to compensate for any unequal wearing of thev tablet-s f of links, thus securing means to keep the stuit at right angles in feeding. y y

On the bed-plate C, and at right 'angles to the chain, is the gauge Z, with a transverse guide-plate, t,the latter parallel to the chain used to regulate the length of the tenon. A

The movable bed-plate A carries 'a precisely-similarl set of standards, I I, head-plate J, presser-box Hwith shoes k, cutters m fm, pulleys u f, endless vchain'Gr,

chain-way D, with its pulleys, but reversed, or presenting the cutters, presser-box, ehain,1and chain-way toward the set just described.

rlhis bedvplate slides on the ways B, and is conned by the ordinary V-shaped guides, and is movable to or from th'e stationary set by means of the usual device or screw S, running beneath the beds, and terminating in hand-wheel l. v

The driving-pulley F of the chain slides on a spline Ishaft Y, carrying at its left end the tight and loose` pulleys K K,vto which the power israpplied, and also the driving-pulley K', for cutters on that part of shaft beneath the tightener W and cutter-pulleys tra of sta-l tionary hed-plate; also the feeddriving pulley L, which drives the spur-pinion N, which is engaged with the spur-wheel' 0, which, by means of-a smaller wheel, I), engages the spur-wheel Q at the end of the feed-shaft 1t, which carries the chain-pulleys.

The remote end of the shaft Ycarries the pulley X, which moves, with the bed-plate above it.

On a spline, run the cutter-'pulleys u a, and tightener-pulley above it.

Having thus fully described my invention,

lVhat I claim therein as new7 and desire to secure by Letters Patent, is-

In a tenoningmachine, the movable bed-plate A', carrying 'the presser-box H, the chain-feed G, provided with adjustable lugs a, iu combination with the stationary bed-plate O, having like devices, when'all the parts are constructed, arranged, and operated subf stantially in the 'mannerdescribedand for the'purpose set forth. i
